Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large bowl, whisk together 2 cups of all-purpose flour and 1 teaspoon of baking soda.

In another bowl, cream together ½ cup of softened unsalted butter with ½ cup of granulated sugar and ½ cup of brown sugar for 3-5 minutes.

Beat in 1 large egg and 1 teaspoon of vanilla extract until smooth.

Gradually add the dry flour mixture to the wet ingredients, mixing gently until just combined.

Fold in ¾ cup of colorful candy crystals into the dough.

Drop dough onto the prepared baking sheets, spacing them properly, and bake for 10-12 minutes.

Cool the cookies on the baking sheets for about 5 minutes before transferring them to a wire rack.
